I haven't slept for 4 nights. I feel jittery, anxious and restless all over my body. I feel like I'm on some kind of speed. Two weeks ago I had a subtotal hysterectomy and healing fine. Off of all pain meds. 4 nights ago this started and didn't get to sleep until 3:30am, the next night 2:30am, last night 2:30am, but tonight...no sleep at all. This is terrible. I'm not bad enough to go to the E.R. but my breathing is sort of shallow/can't get enough O2 in. My stomach is kind of sour, neck is tense, twitching legs like crazy...I always do that, but it's gotten worse. I doubled up on my Ambien 6.25mg last night, no luck. Took my Lorazepam .05mg (sparingly), no luck. Is this Menapause weirdness? WTH. I'm calling my M.D today but I am greatful for any advice.
